I wonder if there was a reason for changing the filter?
My 2002 +8 had the trumpet intake, a very nice shiney stainless steel one, which is now in my collection of original parts replaced. My car was chipped 12 years ago by John McDonald. When he put it on a rolling road the car was only producing 125 BHP, even after chipping it only increased to 130 BHP. Only when he took the air filter off did it give 203 BHP, the chip was not really for BHP increase but to increase the rev range.It was the air filter causing the problem. I now have a K&N type cone filter which has been fine.
